Application filed November 23, 1908. Serial No. 41:64.1036- To all 4whom it may concern:

Be it imown that i, CLARENCE H. How- Ann, a citizen of the United States, residing at St. Louis, .in the State oi Missouri, have in vented a neuT and useiui improvement in Car-Underrames, of which the ioliowing is a specification.

My invention relates to a cast metal underframe particuiarly adapted. for a raiiroad seit-cleaning dump-car, such as an ore, gondola, or analogous car, and has for its object Ito provide strong, rigid and durable underlframe adapted to form a bottom end support for the uprignt and diavonal side members of the car body and thereby transmit the vertical stress of the ioad therethrough uniformly to entire underirame.

The invention consists in features oi nov'- elty as hereinafter described and claimed, reference being had to the accompanying drawing forming part of this specification, whereon,

Figure l, .is a top plan view of my improved cast instal und rfi-ame adapted for a seliclearing ore dump-car, omitting the car body 5 Fig. 2, a side eievationgthereof show ing the car body thereon broken away; Fig. f3, a vertical longitudinal section through the underfrarne on line 3, 3, in Fig. 1, and corresponding section through the car body; liig. 4, a vertical transverse section through the underframe and car body on line 4, 4, in Fig. 3, and Figs. 5 and 6, detail views of part of the underframe as seen respectively, in Figs. 3 and 4, showing an alternative construction of the said part.

Like letters and numerals of reference denote like parts in all the figures.

a represents my improved car underframe which is composed preferably of cast steel integral throughout and may be of any suitable design as to the number, arrangement, and cross section of its component members, comprisin" preferably, in the present case, two opposite channel longitudinal side members l, a channel member or end sill 2 uniting the side members i together at their respective ends and having its middlel portion preiV` erably, box-shaped and adapted. thcroat to increase the resistance oll the uiulerframe a to end shocks, two opposite longitudinal channei members 3 and intermediate to the side members 1, and united at each end to the correspimding und sill 2, a transverse preferably -shapod member 4 adjacent to each ond sill 2, intersecting at a suitable distance apart.

the intermediate longitudinal members 3 and united at each end to the corresponding side member i, the transverse members 4, which with the longitudinal members 3 form the opening I through the middle and adjacent part of the underfrai'nc a for receiving the lower portion of the hopper c ol the car body as hereinafter' more particularly referred to, constituting the body-holsters and adapted for the application thereto of a suitable draft-gear, such :is d as seen to the ieit in Figs. 1 and f3, and the members 3 and i having preferably, on their inner or opposite sides, gussets 5 at their junction with each. other, the members l and being united togetlier respectively, at a suitable distance from the center of the under-frame o by transverse channel members o, and the longitudb nai4 members 23 united to each other at the middle by a preferably, L-shaped transverse bar 7 lhaving its apex alined to the transverse center of the underframe a and its iianges respectively inclined downward on each side of the said center at an angle oi 15", the bar r7 having, on the inner side of each flange, lugs 8 to which the drop-doors e ol' the hopper c are hinged as seen in Fig. 3.

Projecting from the outside ol` each side member l and integral therewith are l'ornied a series oi` l1orizontal brackets 9 which are adapted to support, and. on which the bottom ends oi' the upright posts f of the car body bear, the posts f being res )ectively, guided or maintained in a verticai position by lateral upright webs 9 which are integral with the brackets 9 and side members l, while from theoutside oi' the webs 9 along the side members 1 and integral therewith, project horizontal brackets 10 which are adapted to support and bear against the bottomA ends oi the diagonal braces g of the car body, the brackets 10 being arranged respectively, on one or both sides ol' the brackets 9 with their laterai upright webs 9, according to the disposition of the diagonal braces g as shown in Figs. 1 and 2, and the brackets S, webs 9", and brackets l() having suitable outside strengthening ribs 1l integral therewith and with the side members 1 substantially as shown. Furthermore, on the underl'rame a at the junction oi' the end sills 2. and intermediate longitudinal members 3, are formed upwardly projecting pockets 12 for receiving the bottom ends oi the upright ond postsfl (Fig. 3) ofthe car body, and on the side and interi'nediate iongitudiilal mem- '.'Jivf-ots l5, or otherwise, as shown in rigs. 5

bers l and Il adjacei'it to the pockets 12, are y termed pockets lli which are integral with 'the said members and adapted to receivel the bottom ends oll the end diagonal braces g.

l" rom thi underside ot, and prel'erably integral with each intermediate longitudinal member l5 adjacert to the bottoni outlet `i-t from the hopper i: at each sideol', and eqnidistant l'rom the transverse center line ol the undeafl'rai-ne c, depends a suitably shaped bracket l5 l'rom which projects laterally a pocket lo beneath the opening the pocket 16 being adapteo to receive and hold the co1'- responding end ol' a bar li. which lorms the bottom transverse sill ol' 'the inclined end `wall l? of the hopper c, and against which the drop-door e is closed as seen in Figs. 2 and Or it' desired the bracket l5 with the pocket lo in lieu ol' being integral with the under-trame o as described, may be of i separate construction and ixed thereto by l and la'.

ln the above construction oll underl'rame, by supporting)- the upright posts f and diagonal braces g einlwise upon the brackets 9 and li), which are interral with the underl'rame a., the vertical stress ol' the load within the hopper c upon the said osts and braces is transmitted therethroug 1 directly to and uniformly through the entire underl'ramc; moreover, by uniting the ends ol' the hinge-bar 7 l'or the drop-doors ol' the hopper c to the intermediate longitudinal mein-bers 3 oi the onder-trame (L the latter is greatly strengthened at its middle or weakest part and its resistance thereat to the lateral stress ol' the load increased, and furthermore, by fixing the bottom outlet sill It ol' the hopper c `in'pockets having their walls integral with the underl'rame, the hopper c is greatly strengthened and rendered more durable ther-eat, and positive, ,-losing olI the dropdoors c. insured at all times.
